Genes affected
PEX1 (HGNC:8850): (peroxisomal biogenesis factor 1) This gene encodes a member of the AAA ATPase family, a large group of ATPases associated with diverse cellular activities. This protein is cytoplasmic but is often anchored to a peroxisomal membrane where it forms a heteromeric complex and plays a role in the import of proteins into peroxisomes and peroxisome biogenesis. Mutations in this gene have been associated with complementation group 1 peroxisomal disorders such as neonatal adrenoleukodystrophy, infantile Refsum disease, and Zellweger syndrome. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2013]

Zellweger spectrum disorders Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Mar 17, 2020 | For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in PEX1 are known to be pathogenic (PMID: 9398847, 16086329, 16141001, 21031596). This variant has been observed in individual(s) with Heimler syndrome (PMID: 27302843). ClinVar contains an entry for this variant (Variation ID: 224324). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Thr598Glnfs*11) in the PEX1 gene. It is expected to result in an absent or disrupted protein product. - |
